Recalling the Single-FFT Direct Poisson Solve

Conference Paper, Proceedings of ACM SIGGRAPH '08 (Poster), August, 2008

Abstract

Large Poisson’s equation problems arise in gradient-domain image compositing. Agarwala [2007] and Kazhdan and Hoppe [2008] recently presented iterative solution methods using a smooth correction term and multigrid with higher-order elements, respectively. In both papers, however, direct solution methods are somewhat glossed over. This work aims to remedy these omissions by presenting timing numbers for a classic single-FFT – so-called because it performs a fast Fourier transform only on one dimension of the image – solution method.
